replacement for Biltbest window crank mechanism operator for casement windows

A quick learner from San Diego, Ca says:

The cranks on several of my Biltbest casement window operators no longer crank the window in and have come out of the main body of the mechanism. I can play around with it and crank the window out, but not back in, because the crank just comes out of the gear. Please see attached photo. The width of the opening in the wood where the gear mechanism fits is just under 5". Do I need to take off the wood trim to replace the whole operator? Do you have replacement parts for this item. Thanks

Thank you for posting! Please see our 39-031 & 39-032. I think these look pretty similar, but check it out and let me know what you think. You will have to remove the wooden trim in order to replace this operator.

I have some 30 year old Built Best crank windows.The crank handels have come out of the gears. Is there a way to fix the existing crank or do I need new ones like 39-032.

Once the worm gear comes out, it's unfortunately not possible to repair it. That usually means the gears have been stripped out. You will need an all new operator.
